PURPOSE
To compare postoperative clinical outcomes between 2 types of 3-piece aspheric intraocular lenses. METHODS: Uncorrected visual acuity, best corrected visual acuity, total ocular and internal ocular aberration including higher-order aberrations and spherical aberration, and modulation transfer functions were compared 6 months after cataract surgery between eyes implanted with TECNIS ZA9003 (group 1) and HOYA PC-60AD (group 2) in 30 and 28 eyes, respectively, In addition, the differences between postoperative spherical equivalent and preoperative target refractive errors were analyzed. RESULTS: Clinical outcomes showed no significant differences between both groups including visual acuities, high order aberrations, and modulation transfer function. In both groups, postoperative refractive errors were more of a myopic state than preoperative estimated target refraction. The myopic refractive error between both groups showed no significant difference (-0.26 vs. -0.42 diopter, p = 0.75). CONCLUSIONS: The newly developed 3-piece aspheric IOL, HOYA PC-60AD shows similar clinical outcomes compared with the widely used 3-piece IOL TECNIS ZA9003. |
